White was arrested Sunday on an outstanding theft warrant. He was found in a homeless assistance center in Homestead, Fla, according to a statement released Tuesday by the Camden County Prosecutor’s Office.

He is now being held in Florida. Authorities said White told a Prosecutor’s Office investigator and a Camden detective that he assaulted Brito-Reyes and struck her with the handgun at her home.

He then allegedly used her ATM card at a Mount Ephraim Wawa to take $500 from her account before fleeing the area.

A relative of the victim found Brito-Reyes dead on June 4 in a second-story bedroom of her home in the 3000 block of Hartford Road in Camden. Investigators said she’d suffered fatal injuries to her head and neck.

Family members told investigators Brito-Reyes and White had been in a relationship for 15 years. She was in the process of breaking up with him when the killing occcurred, and White had threatened to kill her if she did so, the family members said.
